MongoServerError: E11000 duplicate key error collection: PigeonProjekt.users index: email_1 dup key: { email: "email#gmail.com" }
index: 0,
code: 11000,
keyPattern: { email: 1 },
keyValue: { email: 'email#gmail.com' }
could someone help me solve this problem.

If you can, try dropping the database or the collection itself then test again. If you first set the email field to unique: true and then inserted the user that you have in the database, but later changed the unique value of email to false in your schema, this will not update the collection itself. In short, rules in the database for email unique: true still apply and you need to remove them.

ExpressJS - can't get data on update User

I want to create an experience array in User model with new data, and the problem is that I don't get saved data in exec function so I can push new data in array on frontend. This is what I got so far.
router.post('/:username/experience', function(req, res) {
const username = req.params.username;
User.findOneAndUpdate(
username, {
$push: {
experience: req.body
}
}, {
safe: true,
upsert: true
})
.exec(function (err, data) {
console.log(data, "------>");
});
})
This is my schema for experience, which is called in User model like experience: [ExperienceSchema].
const ExperienceSchema = new Schema({
title: {
type: String,
required: true
},
company: {
type: String,
required: true
},
from: {
type: Date,
},
to: {
type: Date,
},
workingNow: {
type: Boolean,
default: false
},
description: {
type: String
}
}, {
usePushEach: true
})

Since findOneAndUpdate returns the original document (state before update) you need to add new: true to the options in order to get the updated document.
options:
{
safe: true,
upsert: true,
new: true
}

how to add a new record to postgresql database using sails v.1?

I'm trying to add a new user to the users' table that I have in PostgreSQL database. there is no problem when I use findOne() method but when I use create() nothing happens. here is some of my configuration:
model(users.js)
var bcrypt = require('bcryptjs');
module.exports = {
tableName: "users",
attributes: {
id: {
type: 'number',
unique: true,
autoIncrement: true,
},
first_name: {
type: 'string',
required: true
},
last_name: {
type: 'string',
required: true
},
email: {
type: 'string',
required: true,
unique: true,
isEmail: true
},
password: {
type: 'string',
required: true
},
},
}
usersController.js
registerUser: function (req, res) {
bcrypt.hash(req.body.password, 10, function(err, hash) {
if (err) return res.send('An error occured', 500);
console.log(hash);
// Save user to the database
Users.create({
first_name: req.body.first_name,
last_name: req.body.last_name,
email: req.body.email,
password: hash
}).exec(function(err, user){
if (err) return res.send('An error occured', 500);
console.log(user)
})
});
}
and i set my datastore.js file to:
default: {
adapter: require('sails-postgresql'),
url: 'postgresql://username:password#host:5432/db-name',
},
and finally, in my models.js in config folder, i set migrate:'safe' and i commented the schema and attributes.
module.exports.models = {
// schema: false,
migrate: 'safe',
attributes: {
// createdAt: { type: 'number', autoCreatedAt: true, },
// updatedAt: { type: 'number', autoUpdatedAt: true, },
// id: { type: 'number', autoIncrement: true, },
//--------------------------------------------------------------------------
// /\ Using MongoDB?
// || Replace `id` above with this instead:
//
// ```
// id: { type: 'string', columnName: '_id' },
// ```
//--------------------------------------------------------------------------
},
dataEncryptionKeys: {
default: '/ZBj9EC29Xb+mNULkmFn3NuYUK9wDLJdWQ4U2lNR7+w='
},
cascadeOnDestroy: true
};
every thing seems to be ok but i don't know what the problem is?

Model methods are not working in sails js

I am using sails v0.12 , I have different models in my MySql relational database but the area of concern lies in these 2 models which are
1. User
2. Appointment
I want to add apptCustomer and apptProvider data into appointment model
but the value is NULL in the database
My User model is :
module.exports = {
attributes: {
name: {
type: "string",
},
email: {
type: "email",
required: true,
unique: true
},
contact_no:{
type: "int",
maxLength: 15,
//required: true,
},
address: {
type:"longtext",
//required: true,
},
userId:{
type: "string",
primaryKey: true,
unique:true
},
gtoken:{
type: "string"
},
provider:{
type:"string"
},
cancel:{
type: "boolean",
// required: true
},
business_name:{
type:"string",
unique:true
},
business_category:{
type:"string"
},
roles:{ // Many to Many = User <-> User-role <-> Role
collection:'Role',
through:'userrole',
},
services:{
collection:'Service',
through:'serviceprovider', // Many to Many = User (provider) <-> Service-provider <-> Service
},
schedules:{ // One to One = User (provider) - Schedule
collection:'Schedule',
via:'owner',
},
providerAppointments:{ // One to Many = User(customer) - multiple Appointments
collection:'Appointment',
via:'appProvider',
},
customerAppointments:{
collection:'Appointment', // One to Many = User(provider) - multiple Appointments
via:'appCustomer'
}
}
};
And my Appointment Model is
module.exports = {
attributes: {
appointment_id:{
type:'int',
primaryKey: true,
autoIncrement:true
},
appointmentDate: {
type: 'datetime',
required: true,
},
start_time: {
type: 'string',
required: true,
},
end_time: {
type: 'string',
},
status: {
type: 'string',
enum: ['booked', 'canceled']
},
appProvider: {
model: 'user',
},
appCustomer:{
model: 'user',
},
serviceAppointment: {
model: 'service',
}
}
};
And my Model Methods are as follows
Appointment.findOrCreate({appointmentDate:req.body.values.appointmentDate, start_time:req.body.values.start_time, end_time:req.body.end_time, status: status},{appointmentDate:req.body.values.appointmentDate, start_time:req.body.values.start_time, end_time:req.body.end_time, status: status})
.exec(function apptCreated(err,appt){
if(err) { sails.log('err',err)}
Service.findOne({ service_id : req.body.values.selected_service})
.exec(function(err,service){
service.serviceAppointments.add(appt);
service.save(function(err,result){
if(err) { sails.log(err)}
})
}),
User.find({userId: req.body.businessId})
.populate('roles')
.exec(function(err,provider){
_.map( provider.roles, role => { // Problem lies here .. this method is not working
if(role.role_id==1){
provider.providerAppointments.add(appt);
provider.save(function(err, result){
if(err) { sails.log(err)}
sails.log('appointment added to provider')
})
}
})
}),
//Appointment adding to Customer
User.find({userId: req.body.customerId})
.populate('roles')
.exec(function(err,customer){
_.map( customer.roles, role => { // Problem lies here... this method is not working
if(role.role_id==2){
customer.customerAppointments.add(appt)
customer.save(function(err, result){
if(err) { sails.log(err)}
sails.log('appointment added to customer')
})
}
})
}),
// Adding contact to customer
User.update({userId: req.body.customerId},{ contact_no: req.body.values.contact_no}) // this method works fine
.exec(function userUpdated(err, user){
if(err) { return sails.log(err)}
sails.log('contact number updated',user);
})
})

As far as I can see, at the moment that you call provider.providerAppointments.add, provider.providerAppointments is still just a regular property - possibly an array of ids.
I think you need to add .populate('providerAppointments') to your User.find... if you do that, then provider.providerAppointments should have a .add method that works the way you expect.
Of course, if this is the source of error, I would have expected a pretty clear error message, like provider.providerAppointments.add is not a function or some such. But try adding the populate, see if it fixes your problem.

I can't establish a simple association on Sails.js (relation model's field shows undefined)

I've been trying a simple 'one way association' on v0.9.16 and later v.10.0.rc8.
I'm guessing, I'm doing something wrong.
I have two collections on my MongoDB and I have two models and a controller such as following;
my User.js file;
module.exports = {
connection: 'mongo',
attributes: {
username: {
type: 'string',
required: true
},
encryptedPassword: {
type: 'string' ,
required: true
},
//one way association
personel: {
model: 'Personel'
}
}
};
my Personel.js file;
module.exports = {
connection: 'mongo',
attributes: {
name: 'string',
phone: {
mobile: 'string',
office: 'string'
},
email: 'string',
gender: 'string'
department: {
department_id: 'integer',
department_name: 'string'
},
title: {
title_id: 'integer',
title_name: 'string'
}
}
};
my UserController.js file;
module.exports = {
show : function (req, res) {
User
.findOne(req.param('id'))
.populate('personel')
.exec(function(err, user) {
console.log(user);
});
}
Console writes 'undefined' for personel field;
{ username: 'jkidd',
personel_id: '1',
personel: undefined }
Edit
To provide association I've just added following codes to my User model
//one way association
personel: {
model: 'Personel'
}
and I'm trying to
show : function (req, res) {
User
.findOne(req.param('id'))
.populate('personel')
.exec(function(err, user) {
if(err) return res.json(err, 400);
if(!user) return res.json({ error: 'No User with that Id' }, 404);
console.log(user);
res.view({
user : user
});
});
}

You missed the Association in your Personel.js:
module.exports = {
connection: 'mongo',
attributes: {
department_id: 'integer',
department_name: 'string',
owner: {
model: "User"
}
},
}
See for more Info: http://beta.sailsjs.org/#/documentation/reference/Models/Associations/OnetoOne.html
Hint: You dont need to config the _id - waterline handle that for you!
Edit:
Also a Issue
And you cannot use "nested attributes" (see: How to translate models in Sails.js?). Change that also!
edit: you almost there... ;-)
module.exports = {
attributes: {
username: {
type: 'string',
required: true
},
encryptedPassword: {
type: 'string' ,
required: true
},
//one way association
personel: {
model: 'user'
},
},
};
and your personel.js
module.exports = {
attributes: {
name: 'string',
email: 'string',
gender: 'string',
owner: {
model: 'user',
},
},
};

I wanted to add a comment but cannot as my rep isn't high enough. As already stated. You missed the Association in your Personel.js.
With this in place waterline should link the models up but it isn't for some reason. I'd suggest removing your id attributes as these are likely confusing matters as you'll get _id added automatically for you which is what waterline will use for the associations.
In your code where you associate the personnel to user do so by setting user.personnel = personnel.id.
If you require more help can you post the code/commands you're using to associate the models too.
[EDIT]
With regards to nested attributes check Sails.js - how to update nested model
Your User model should be as follows:
module.exports = {
attributes: {
username: {
type: 'string',
required: true
},
encryptedPassword: {
type: 'string' ,
required: true
},
//one way association
personel: {
collection: 'personel',
via: 'user',
},
},
};
And your personel model:
module.exports = {
attributes: {
name: 'string',
email: 'string',
gender: 'string',
user: {
model: 'user',
},
},
};
And just a little modification to your controller so that you can view the JSON output in browser:
module.exports = {
show: function (req, res) {
User2.find()
.populate('personel')
.exec(function(err, user) {
console.log(user);
return res.send(200, user);
});
},
}
[EDIT]
I've just realised you weren't talking about a one to many association, the above is that, not a one to one.
Your edited code looks find for the one to one join. How are you creating the models? I think that's your issue, you need something like:
Personel.create({ name: 'personel'}, function(err, createdPersonel) {
User.create({ name: 'user', personel: createdPersonel.id }, function(err, createdUser) {
res.send(200, createdUser )
}
}
That's without error checking and assuming you're in a controller.
